In this study, graphene powders were crushed to smaller particles via cryomilling. The cryomilled graphene
powders were characterized by XRD, Raman spectroscopy, TGA, and SEM. Tensile tests were performed
on raw graphene/chitosan and cryomilled graphene/chitosan nanocomposites in order to
investigate the cryomilling effect of graphene on the tensile properties of their corresponding nanocomposites.
The results showed that cryomilling enhanced the dispersion, graphitic characteristics, and thermal
stability of the graphene powders. Cryomilling graphene also showed that their corresponding
chitosan nanocomposites had significant improvement in tensile properties compared to raw graphene/chitosan
nanocomposites.
